Last night I was told by the owner of Red Hen in Lexington, VA to leave because I work for @POTUS and I politely left. Her actions say far more about her than about me. I always do my best to treat people, including those I disagree with, respectfully and will continue to do so

Some applauded the restaurant owner’s decision – but others decried the move, including the president himself.

“The Red Hen Restaurant should focus more on cleaning its filthy canopies, doors and windows (badly needs a paint job) rather than refusing to serve a fine person like Sarah Huckabee Sanders,” Trump tweeted. “I always had a rule, if a restaurant is dirty on the outside, it is dirty on the inside!”

The dining debate is just the latest incident that’s posed the question of when taking a moral stand crosses the line into incivility.
